 ac not working
I have a 98 318ti auto. The a/c will not come on. Car ran hot, had a defective auxiliary fan and cracked plastic pipes. Replaced pipes and T-stat and bled system runs good not over heating. Auxiliary fan was replaced with wrecking yard unit, close but not exact. Original has blue, tan and black with blue stripe. Replacement has red, green and black wires. Low speed fan comes on at idle when needed. THE A/C DOES NOT COME ON NOW!!! It did, with high speed fan a couple of times. The fuse under the dash has blown several times, before and after auxiliary fan replacement. The green a/c light comes on, warm air blows from vents but the compressor does not ingage. I have jumpered out the compressor to 12 volts to test and it does spin. I am melting here in Alabama so any help would be welcome. Thank you in advance,
